A rare type of coin in the form of a forgery / copy - a ten-dollar coin with Sobieski.
Very nicely made, most likely minted, bleached / silvered superficially.
At the eagle's paw there is a visible trace of scratching / cuts, perhaps to mar the punch present there (as on item 4359).
Weaker made border.
White, non-magnetic metal, diameter 33.5 mm, weight 17.28 g.
